Miguel Ullola is a relief pitcher for the Houston Astros. In 2026 he struck out 15 batters over 15.2 innings across 10 appearances, going 2-0. His ERA of 2.30 is 45.0% lower than the league average of 4.18. Stripping out defence, his 4.00 FIP suggests that his ERA had some help behind him. He missed bats on 27.9% of swings (13.3% of every pitch he threw), walked 6.9% of the batters he faced and struck out 25.9%. His 0.1 dbWAR is built from that FIP rather than runs allowed, so it credits him for what he controls and not for the defence behind him.

wOBA uses linear weights measured from this season's own play-by-play rather than published constants, and wRC+ is park-adjusted against that same league. dbWAR is our own open implementation — not fWAR or bWAR — and the full derivation, including its simplifications, is on the methodology page.
